I got some new wiseco pistons and gapped my ring to the spec that I need them to be. I looked at the sheet and called wiseco and verified the ring gap that I chose was correct which is I think was 0071 top 0073 bottom x 3.425, but what I wanna know is since that gap spec is for 15-30 psi and I’ll be running 16-18 which is on the low side if that spec will I have lots of blow-by?

 

Not likely.
